1 ) CjOverkill now ships encoded with Zend and IonCube.
2 ) CjOverkill now tries to enforce a correct error_reporting setting in case the server has an unproperly configured php.
3 ) The toplist generation setting is now properly shown.
4 ) A specific function has been implemented in order to sanityze variables in the admin panel. This prevents some integrity errors under specific PHP configurations.
5 ) Fixed a bug that prevented proper trades copying from one site to another when MySQL was not returning properly escaped strings.
6 ) Fixed a small bug that was reporting incorrect Country Log OUT values for special trades under specific PHP configurations.

To upgrade just replace all your CjOverkill files except the cj-conf.inc.php and then login into your cjadmin. Follow the upgrade wizard instructions and you are done.
